Description

Audio socket connector

This creation is about an audio jack connector, especially a light, short, and versatile audio jack connector.

An electronic connector application generally has a socket and a plug disposed in an electronic device, the plug being plugged into the socket to complete the signal connector.

An audio jack connector having an audio effect is widely used in audiovisual audio products, and its main function is to provide transmission of voice signals. With the continuous development of electronic products such as mobile phones, PDAs, MP3s, and notebook computers, the design requirements for audio connectors are becoming higher and higher.

A conventional four-pin audio connector plug has two specifications, one is MGRL, which is sequentially a microphone 埠, a ground 埠, a right channel 左 and a left channel 埠, and the other is a GMRL. Grounding 埠, microphone 埠, right channel and left channel 埠, while current audio socket connectors are designed to be larger in size, because the metal housing and signal terminals of the connector are not properly laid out. The metal housing and the fixed holding structure of each signal terminal become the biggest obstacle to the thinning of the connector, because the fixing stability of the terminal is limited by the volume of the connector itself, so that the fixed position of the terminal is limited, thereby increasing the connector volume to achieve each Fast positioning of a signal terminal. At the same time, the assembly structure of the metal casing needs to be adjusted. Therefore, in order to meet the requirements of lightness and shortness, how to design the microphone terminal, the grounding terminal, the right channel terminal and the left channel terminal of the socket in the socket insulation body under the requirement of a certain size and size, and how to have a mask The functioning metal casing is mounted on the surface of the insulating body, which is a problem to be overcome.

In view of this, the creator created the audio socket connector of the utility model in the spirit of excellence and breakthrough in innovation.

The main purpose of this creation is to provide an audio socket connector, the arrangement of the signal terminals and the reasonable fixing of the metal casing, making the connector lighter, thinner and more practical.

The present invention mainly provides an audio socket connector, comprising an insulative housing, a plurality of signal terminals fixed to the insulative housing, and a metal housing covering the surface of the insulative housing, wherein the metal housing has a flat portion, the flat portion The first and second buckle arms and the third buckle arm are respectively disposed on the front and rear sides, and are respectively fastened on the insulating body, and the first, second and third buckle arms are triangularly distributed, first and first The two snap arms are in a straight line and are parallel to the third buckle arm.

With the above technical solution, the metal casing having the fixed structure can be matched The complex signal terminals are more compactly positioned in the insulating body, which effectively reduces the space occupation rate of the connector and meets the requirements for thinning of electronic devices.

The above-mentioned objects, advantages and features of the present invention will be more fully understood from the following description of the preferred embodiments.
